 (videolan ticket 8145)
 A vlc user uploaded a DVB recording from TTV HD (Taiwan) explaining that
 when this broadcast station went on-air, set-top-box provider had to
 update their firmware to support decoding.
 FFmpeg only decodes the first frame, WMP plays the stream recognizable but
 with heavy motion artefacts.
